Improvement in wood pavements



- the spaces between HENRY M BEIDLER, OF PHILADELPHIA, PENNSYLVANIA.

Letters Patent No. 111,425, dated January 31, 1871.

IMPROVEMENT IN WOOD PAVEMENTS.

The Schedule referred to in these Letters Patent and making part of the same.

To all whom it may concern Beit known that I, HENRY M. BEIDLER, of Philadelphia, in the county of Philadelphia and in the State of Pennsylvania, have invented certain new and useful Improvements in Wooden Pavement; and do hereby declare that the following is a full, clear, and exact desciiption thereof', reference being had to the accompa` nying drawing and to the letters of reference marker thereon making a part of this specification.

The nature of my invention consists in the construction and arrangement of a sectional wooden pavement, as will he hereinafter more fully set forth.

In order to enable others skilled in the art to which my invention appertains to make and use the same, I'will now proceed to describe its construction and operation, referring to the annexed drawing, in whioh- Figure 1 is a side view;

Figure 2, a -plan view; and

.Figure 3, an end View of one section of my pavement.

Each section of my pavement is composed of a series of wooden blocks, A A, placed eudwise up and down, as shown in 'the drawing, to form one section of the desired dimensions.

Lengthwise through the section, at the bottom, run

boards orbl'ocks B B, of suitable thickness, to keep the blocks A A at proper distance apart; and the` blocks A A, on each side of the boards B, are placed at the same or nearly the same distance apart, as shown in tig. 2.

The blocks A and B are then secured together' lby means of dowelLpius u u, which may either run clear through or only partially through the section.

It will be seen that in this manner there is left. a space between all the blocks A A for a suitable distance down, which spaces are to' be filled with gravel packed down. This lling is, however, not intended to run all the way down to the bottom of the blocks A.

Lengthwise through the section the boards or blocks B B prevent it (the gravel) lfrom going.down,`bnt in the blocks on each side of the boards there is nothing "to prevent the gravel from settling down.

To obviate this difficulty I place strips C G, in the l manner shown in fig.2 so as to partially close up said spaces; that is, close them up at about the same height as the upper edge of the boards or blocks B, so as to prevent the gravel from settling down, but allow the water to pass downward between the blocks A A.

To facilitate the passage of water the boards or blocks B are cut with notches b (shown in fig. 2) at the spaces between the blocks A A.

lhe section thus made is placed on the bed prepared for the saine, and fastened by means of pins D D of wood or'iron passing through the corner and center blocks and driven into the ground.

In place of square blocks I may use round blocks, connected substantially as described above.

A pavement made in this way, of sections, is chea'p and easily made, and any number of sections may be readilytalren up when necessary for thc putting down .of water or gas-pipes.

Ii' any section of my pavement should, by wear or from other causes, give o1' rock, itcan easily be remedied hy boring a hole through one or more of the blocks A and putting down additional pins D, which will securely fasten the section.

Having thus fully described mydnvention,

\VhatI claim as new, and desire to secure hy Letters' Patent, is-

l1. The boards or blocks B B provided with notches b b, and the strips O O, arranged as described, in connection with the blocks A A, substantially as and for t-he purposes herein set forth.

2. A wooden pavementmadein,seetions, composed of a series of blocks, A, notched boards B, and strips C, the blocks A being arranged slightly apart, and

' connected together by the pins a, and to the earth by the pins D, all substantially as and for the purposes set forth. Y

In testimony that I claim the foregoing I have hereunto set my hand this 12th day of January, 1871.

' H. M. BEIDLER.
